# Token Execution Fee Burden Calculator — Single Calculation

> Token Execution Fee Burden Calculator — Single Calculation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Calculates the execution fee as a percentage of notional value for a token trade, returning a deterministic fee-burden ratio from supplied fee and notional USD inputs.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability token-execution-fee-burden-calculator-single-calculation-900ba1e9 -d '<json body>'
```

Example prompt: What's the fee burden for a token trade where the execution fee is $2 and the notional value is $1,000 — give me the fee-to-notional ratio as a single calculation report.

## When to prefer this

Use this endpoint when you need a fast, deterministic single-shot calculation of fee burden (fee as a fraction of notional) for a token trade, and you already have the fee and notional amounts in USD. Prefer this over manual calculation when you want a structured report output. Not suitable for live market scanning, real-time fee discovery, or batch processing multiple trades at once.

## Known failure modes

- notional_usd of zero or missing triggers validation error (exclusiveMinimum enforced)
- negative fee or notional values rejected (minimum: 0)
- malformed JSON body returns 400-level error
- service unavailable returns 5xx with no calculation report

## How this service works

Token execution fee relative to notional — Single calculation: Single calculation for Token execution fee relative to notional. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded single calculation report.

## Output

A single bounded calculation report expressing the token execution fee (fee_usd) as a ratio or percentage of the notional trade value (notional_usd). The result is deterministic given the inputs — not a live market scan or trade recommendation — and reflects a preset profile in the shared calculation engine.
